Photography Camera hacking

Ive bought a new camera!

But more importantly for right now, my old camera didnt focus any more, so I thought I might pull it to bits to see if I could fix it.

A camera hack if you like.

Well its hacked now.

But in the process of attempting to fix it, I thought it might be grit or something stuck in the focus gears. I figured I might be able to override the emergency shutdown on lens fail, and just use brute force to get past the grit.

But before pulling it apart I thought Id look for a software hack to manually focus the thing. Its a Canon Powershot A490 point and shoot (or at least it was), so it doesnt normally have manual focus.

I found much more than a focus hack, but also much less.

Much less in that I still couldnt do manual focus, but so very much more in that I found CHDK - Canon Hack Development Kit.

CHDK is amazing. Its a kit full of files that you install onto your SD memory card, put it into your camera, then use the update firmware option (only seen on my camera when the CHDK is on the card) of your camera to install all the new functionality. It does things like...

• motion detection
• increment focus to automate focus/photo stacking as mentioned in the previous post
• depth of field calculator
• exposures from 2048s to 1/60,000s with flash sync
• change the layout and visibility of you on screen display info
• etc etc etc (so much more)

Look here to see a slightly bigger list, but still not all of it.

And here for the manual which covers more.

But even more can be found on the forum in the form of scripts that can be loaded into your camera. There are scripts that do motion detection fast enough to catch lightning strikes. (less than 60ms I think it was - dont quote me)

So in spite of just buying a new camera, Im off to see if the $20 camera I saw in the electronics shops bargain bin is a cannon powershot.

Aquaponics Cucumber

Cucumber.

Strange word.

Anyway, Ive been getting good results with hand pollination. For some reason the female flowers (the ones with the fruit attached to the back of them, open well, but the males dont.

I thought bees were supposed to do this work. There are no bees anywhere doing anything. Is there a strike or something. Perhaps people are talking about it on TV. Maybe there is a reason to watch TV after all.

I planted my four cucumber plants in the corner of the growbed nearest the door. The door stays open for summer, so I trained the plants to grow outside.

Actually it doesnt really matter if the door was open or closed, they could be made to grow under the door with a little pruning.






Ive been using a small, soft artists paint brush to tickle all the flowers on my plants and do the bees work for them.

Every female flower Ive hand pollinated has produced a very tasty fruit, but none of those that I left for the bees have manage to set fruit.

There seems to be a lot of fruit. More than we could use, but they are finding good homes with friends and relatives.

One even went to a friendly relative.

Thinking Bacon

I thought it was just me that was a big bacon fan, but lately Ive been seeing bacon T-shirts, bacon poems, bacon coffee mugs etc everywhere I go online. Which brings me to remind myself how the net works. If I do a search on google, I see things that google thinks Im interested in. That means that if there is even the slightest connection to bacon, I get a lot of bacon hits. Everything I search for adds to the database of things Im interested in, so google thinks that even a tenuous connection is worth reporting, because Im clearly interested in bacon AND electronics.


If I do the same search on someone elses computer, I get different results.

One of the side effects of getting good search results that are relevant to the searcher, is that there is no editor to decide on the things that everyone is interested in. That tends to mean we keep a tight lid on broadening our horizons. One role of a TV news editor was to decide that say, an impending asteroid impact about to wipe us all out, was important to even people who were only normally interested in puppies and real estate. This, because it might impact their desire to buy more puppies or real estate, or might just be worth knowing about in spite of their desire to buy more puppies and real estate.

Google never includes impending asteroid impacts in search results for "haberdashery" on your grand parents computer.

A good haberdashery magazine editor might at least mention in passing thats its worth buying some extra buttons to see you through the coming asteroid induced ice age.

Im guessing magazines are a weigh point on that path, from hearing about things to only hearing about our obsessions.

The net can be an amazing way of gaining information, but it can also be a trap, set to turn us back on ourselves, and blindly confirm that which we already believe to be unconditionally true.






120 Things in 20 years is just reminding itself to wake up and smell the bacon.
